2020 Massimo T-Boss 410 Overheating

[Tiff Rumsey]

I own a 2020 T-Boss410 I'm having problems with it over heating with it just idling for maybe 10 minutes, I have checked the fan and it works. I wired the fan up to a switch so it runs all the time and it still over heats within 10 minutes. Anyone have suggestions?

I would guess that there is air in the coolant. There are bleeder screws for this, and you have to raise the front end somewhat. I have a 2019 T-boss 410. Haven't had any trouble with it so far. You may also check the thermostat to see if it's working properly.

Any chance you could tell me where the bleeder screw is?

[T-boss 410]

Well, I can't seem to locate that info. I had it, but now I can't find it.

There's a section here that has downloadable service manuals for the T-Boss 410. You can try there, but I don't know if there were any design changes from the 2019 to the 2020.

Is it a Linhai engine?

[Tiff Rumsey]

Yes it is a linhai engine

Can anyone else here help? I know I had the info on the bleeder screws, but I can't locate it. I searched through the service manual, but I didn't find anything there.

ahhh... the dreaded Massimo leaky head gasket syndrome ... I know it well .. Exhaust gas leaks into coolant blocking its flow with a big air pocket in the head .. Coolant does not circulate.. overheats.. .....when the hot indictor shows, is the radiator cold?   

[Joe Breaux]

the bleeders on mine are on top of head on thermostat housing and underneath the engine at the waterpump ..... But if you have air, theres a reason.... headgasket

Wasn't the head gasket issue confined to the Hisun engines?

[Joe Breaux]

I wouldnt bet on that.. ITS MASSIMO! ...Is your radiator very hot when engine overheats?  If  your fan is running, and radiator is not as hot  as engine its either head gasket or Thermostat is stuck closed if it has one..   Just my experience with their engines
